This is a pack of JConcepts Dirt-Tech 83mm 1/8 Buggy Closed Cell Inserts. JConcepts has upped the ante with the release of the Dirt-Tech closed cell inserts. Gray in color, these inserts are designed in conjunction with tire insert guru, Brian “Dirt” Kinwald to bring the ultimate touch and feel while providing utmost durability. The 1/8th buggy insert has medium sized cuts on the outside which touch off against the tire inner carcass providing a cushy response and feel. The inside has horizontal channels cut in a 360 pattern to soak up the large impacts and help create forward bite and increase acceleration.

The JConcepts design, with custom sculpted features, are blended into the material providing racers a durable option capable of being used in medium to extremely high-traction conditions. Testing has shown great results when used in these conditions and in popular tires such Hybrids, Stackers and Crossbows. Most recently, Ryan Maifield scored a 2nd place finish at the 1/8th ROAR Fuel buggy nationals utilizing the Dirt-Tech inserts in a 60 minute A-main event.
